Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978666, here are decompositions:

  • 5 + 4294978661 = 4294978666
  • 107 + 4294978559 = 4294978666
  • 113 + 4294978553 = 4294978666
  • 149 + 4294978517 = 4294978666
  • 353 + 4294978313 = 4294978666
  • 359 + 4294978307 = 4294978666
  • 383 + 4294978283 = 4294978666
  • 443 + 4294978223 = 4294978666

Showing the first eight; more decompositions exist.
